+32 A cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 9, the vertical shift is 11 units down, and the period of the function is 12π/7. The graph of the function does not show a phase shift.
What is the equation of the cosine function described?
+773 For the function described by:
The amplitude of the function is 9, the vertical shift is 11 units down, and the period of the function is 12π/7
y = 9cos(7x/6) - 11
